Windows update not working properly.

Yes - assuming that the Recovery system is still the proper Acer one (and that's possibly questionable).
The other options are
1) reformat/reinstall using legitimate Retail Media and the Key on your COA sticker (cheapest and quickest option)

2) order a set of disks from Acer for your machine (will take a couple of weeks, and can cost
$50 or so, depending on Acer's sales policies, and location)

You can download legitimate Win7 Home Premium with SP1 (mediea refresh) from the links here - Microsoft
- make sure that you get the right language!

Remember to back up all your data to external storage - either procedure used properly will wipe the hard drive clean.

Okay then. I'll probably try to restore to factory defaults and see what happens.
Thank you Sir for assisting me in my troubles and making me aware of my OS being counterfeit. I would never have known otherwise. :)
